V The present invention pertains to fore: 111g presses and 1 slmllar'iapphancesl and concerns more particularly novel and'improved means enabling the bolster. or, support-for the Work of such apparatus to be adjusted With-easeand dispatch, it being. obvious. -'that the required position or location of the V bolster dependsnpon thellength or height of the piece of work to be operated upon; j

One, aiinoi the invention is .to avoid- .a construction-of the usual present type em- J'ployinga :plurality of removable endureplaceable steelpins or-their. equivalents which are designed to fit in holes in the :bol'ster plates anclin the flanges of the frame structure. a v a.

mAu'purposelof the invention isthe pro vision of aconstruction of the general type indicated which has no separate parts which Vmustbe demounted or taken out when admakingof the structure in such a Way that the two ends'of the bolster or support may be adjusted or broughtuto the new vposition i p ;in succession, whereby-oneifen'd of the 'bolster is supported by. i the frame. While the :other or opposite end is. undergoing change of position. I l An added; feature of the invention is an ,oappliance of this chara'cter which :can be manufactured; economically, and hence sold at arelatively'low'priceq; To." ermitlthose skilled 'nthisart to have a ful and complete understandingfof the ,inventioniboth from structural and functional standpoints, a present desirable and preferred embodiment thereof has been il- I l'ustrated'in theaccompanyingfldravving,

" =and'thebolster are capable of slight' relalugs 29, 29 projectlng; laterallybeyondthe faces ofthe frame and on which thetwo, bolster side-plates are adapted to rest and p 6 has agilug or projection 31 grooved at 32onits'1ower or nndpr face and adapted toext'end' throu h any one of a series of rectangular, verticalf,

ls'eparated-holesior apertures 33fpun'ched' out no i . roof I Each such=casting has oppositely extended of the web of the adjacent, upright, channel section 11 or 12 of the main-frame.

In the production of the frame, all of such holes may be punched at the same time,

thus tending toward economy in manufad" ture and in the finished frame these aper-j tures in the two, spaced, frame members are in register as is clearly shown, so that the Ill bolster may be maintained in any one ofa plurality of horizontal positions of different heighths. l

Whenthestructure is inoperative condition, the twoelugs 31, 31 project through the corresponding pair of holes 33, 33 in the frame and their grooves 32, 32 receive those portions of the frame webs just below the.

margins of the holes,-as shown in Figures 1 and 3, hence eliminating any possibility of unintentional displacement of the parts.

' Under these circumstances the bolster sideplatesv rest upon and are sustained by the -It'is' to r ,port or bear the weight ofthe bolster and four lugs; or projections 29, hence relieving the pins or bolts 24, 24 of any strain.

When it is desired to shiftthe bolster either up or down, the operator lifts one end thereof-.Islightly, as permitted by its'loose "connection. with the complemental cross-pin orrbolt '24:, thus removing its load or weight from the pivoted supporting casting, and

then. he swings the latter inwardly freeing its: grooved or. hook-shaped lug from. the frame, elevating such casting the slight required' amount :to, free it from the frame,

hence permitting that end of the bolster to .be raised .or lowered the required entent and the castingylug is then inserted in: a new frame aperture with its groovereceiving a part ofthe web to prevent displacement, all

this/being accomplished without touching theother end of the bolster or its support,

V Then,.inthe same way, such other end of the bolster; may be moved to its new pos1. tion and its hook support properly applied to. I the frame.

- Thus it vwill'beperceived that the position of the bolster or load support may be readily -changed,-rfirst one end and then the other,

without manipulation of any free or -inde pendent parts likely to be lost or misplaced,

the supporting books. or, lugs being free to be swung intoinoperative position as soon as the weight of the bolster is removed from them. a a p be observed that the castings supits load directly and that the cross-pins or bolts may consequently be relatively small in-sizeJ In this patent, a single convenient and satisfactory embodiment only of the invention has been illustrated and described, but

claims, covers other desirable incorporations V of the inventionin feasible physical struc tures, and consequently the invention is'not limited or restricted to the oneembodiment p es ted. 7 I claim:

1.- Ina press structure'of the characterdescribed, the combination of frame having spaced supporting columns of. channel-shape in cross-section, thewebs ofv said columns having registering series of apertures, a bolster having side-plates, rods-.securing'said bolster side-plates together, sleeves on said rods between said side-plates maintaining the latter properly spaced apart,and apair of bolster-supporting castings each loosely pivotally mounted on one ofsaid sleeves and each having a lug grooved on its under face adapted to project through'any one of the aperturesof the corresponding column and receive in its groove that portion of the column web immediately below the aperture to prevent dis-lodgm-ent of thelug. unless it'is raised, each such casting also having oppositely-projecting ledges on which saidbolster side-plates are adapted to. be directly sup-R ported. I v

2. In a press structure. of the character described, the combination of a frame-having spaced supporting columns having webs with registering series of apertures, a bolster having side-plates, and a pair ofbolster-supporting castings loosely hinged on said bol- -ster and each having alu groovedon its under face adapted to pro ect through any one of the apertures of the corresponding column and receive in its groovethat portion of the vcolumn Web immediately below the aperture to prevent dislodgment ofthe lug {unless it' is raised, each such-casting also having oppositely-pro'ectin led es' On which said bolster side-plates are ad pted to be directly supported. 3.
